How to choose a multifunction air fryer oven to suit your kitchen and household

A multifunction air fryer oven can replace several countertop appliances: an air fryer, fan oven, toaster, pizza oven or even a rotisserie. However, marketing promises do not always reflect everyday reality. A large capacity can quickly become cumbersome, an automatic programme does not guarantee perfect results for every recipe, and a wealth of accessories can make cleaning more complicated.

Before making your decision, focus on three things: the space you actually have, the usable capacity and the functions you will genuinely use.

Common pitfalls to avoid before buying

1. Confusing the stated capacity with the usable capacity

A 30-litre appliance can accommodate a 33 cm pizza, several slices of bread or a whole chicken. In return, it needs enough space around it to release heat safely. By contrast, a 5-litre air fryer is perfectly suitable for everyday portions, but becomes less practical when you need to cook several foods at the same time.

Measure the available width, depth and height, then check the ventilation clearances specified in the instructions. A countertop mini oven should remain easy to access and must not be installed against a wall, curtain or heat-sensitive piece of furniture.

2. Being swayed by the number of programmes

A multifunction appliance may display 9, 10, 15 or 21 programmes. This figure says little about its actual versatility. Instead, look at the manual settings, temperature range, maximum timer duration and accessories included.

For greater flexibility, look in particular for oil-free cooking, roasting, grilling, reheating, dehydrating and pizza-cooking functions. Mechanical controls may be sufficient for everyday recipes, while a touchscreen makes selecting preset programmes more intuitive.

3. Overlooking maintenance and safety

Grease splashes quickly build up inside a cavity fitted with heating elements and a fan. A removable crumb tray, easy-to-clean accessories and a glass door that lets you monitor cooking make the appliance much more pleasant to use.

Power also deserves your attention. Models rated at 1 500 to 2 400 W should be plugged into a suitable wall socket, not a multi-way adaptor or an extension lead of uncertain quality. Keep air outlets clear, use oven gloves when handling hot accessories and keep the appliance out of children’s reach.

Technical criteria to check

Capacity and interior layout

  • 5 litres: a format suited to couples, small portions and kitchens where every centimetre counts.
  • 11 to 14 litres: a good balance between footprint and versatility, sometimes with two baskets or an oven drawer.
  • 23 to 30 litres: an appealing capacity for families, pizzas, roasts and cooking on several levels.
  • 45 to 60 litres: a capacity close to that of a supplementary oven, best reserved for kitchens able to accommodate a larger appliance.

The stated volume is not enough on its own. Also check the internal dimensions, the number of racks and whether you can cook on several levels.

Temperature, timer and air circulation

A range of 80 to 200 °C is suitable for many preparations in an air fryer. A fan oven designed for baking, roasting or dehydrating may offer a wider range, for example from 40 to 230 °C.

Hot-air circulation promotes even cooking, but it does not remove the need to follow the recommended quantities. An overfilled basket restricts airflow and can lead to uneven cooking. For delicate foods, a steam function or combi steam oven can help prevent drying out, depending on the settings used.

Accessories and real-world uses

An oven with a rotisserie is useful for chickens and cuts of meat, provided the cavity is tall enough. A model with a dehydration function should be able to hold several racks and maintain a low temperature for several hours. Also check for a drip tray, baking tray, rack and a basket designed to promote air circulation.

Installation and use: checks to carry out

  1. Place the appliance on a stable, level, heat-resistant surface.
  2. Follow the ventilation clearances specified in the instructions, as these may vary from one model to another.
  3. Check that the appliance’s power rating is compatible with your electrical installation.
  4. Do not cover the air outlets, and do not cover the base with aluminium foil if the instructions prohibit it.
  5. Clean the basket, tray and drip tray once the appliance has cooled completely.
  6. For even cooking, avoid overfilling the basket and turn the food when prompted by the programme.

European compliance statements, such as suitability for food contact or applicable markings, should be checked in the product listing and the documentation provided. They do not replace the need to follow the safety precautions.

Frequently asked questions about multifunction air fryer ovens

Does a multifunction air fryer oven use less energy than a traditional oven?

It depends on the power rating, cooking time, preheating time and quantity being prepared. A compact appliance may heat a small volume more quickly, but it is better to compare the power consumption in watts and the time required for each recipe than to rely on a general claim.

What capacity should you choose for a family?

For two people, 5 to 12 litres may be sufficient, depending on portion sizes. For a family, a 23- to 30-litre family air fryer oven offers more flexibility for larger dishes. Models of 45 litres or more are suited to needs similar to those met by a supplementary oven, provided you have enough space and a suitable socket.

How long does an air fryer last?

Its lifespan depends on how often it is used, maintenance, the quality of the accessories and whether the electrical instructions are followed. Avoid knocks to the basket, abrasive cleaning products and grease build-up around the heating elements. Before buying, also check the warranty and the manufacturer’s or responsible party’s contact details shown in the product listing.
